Abstract

Optical pulses at high repetition rates are generated using rational harmonic mode locking and saturable absorber made of graphene nanoparticles in a fiber laser. The pulse generation from the fiber laser is modeled by solving the Generalized Nonlinear Schrodinger Equation. The computation involved varying the various saturable absorption parameters, such as linear and nonlinear absorption coefficients. Experimentally stable pulse trains at 20 GHz and 50 GHz are generated with a pulse width of ∼ 2.7 ps. This result agrees with the simulation.

使用石墨烯可饱和吸收材料产生20和50GHz脉冲串的混合锁模光纤环形激光器

在光纤激光器中使用由石墨烯纳米颗粒制成的合理谐波锁模和可饱和吸收体来产生高重复率的光脉冲。通过求解广义非线性薛定谔方程，对光纤激光器产生的脉冲进行了建模。计算包括改变各种可饱和吸收参数，例如线性和非线性吸收系数。在20 GHz和50 GHz下产生了实验稳定的脉冲串，脉冲宽度为~2.7 ps。这一结果与模拟结果一致。

期刊介绍： Launched in 1990, the International Journal of High Speed Electronics and Systems (IJHSES) has served graduate students and those in R&D, managerial and marketing positions by giving state-of-the-art data, and the latest research trends. Its main charter is to promote engineering education by advancing interdisciplinary science between electronics and systems and to explore high speed technology in photonics and electronics. IJHSES, a quarterly journal, continues to feature a broad coverage of topics relating to high speed or high performance devices, circuits and systems.
